What does this worksheet teach?
⌄
Find integer values that stand for letters, then fill a six-letter sudoku to reveal a math word. The directions on the page read: Find each value. A number in the grid stands for the letter with that value. Fill the grid with letters so each row, column and thick box has all six once. An answer key is included.
Can I use this code breakers worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade math puzzles, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
